Inversion type hydraulic relay elevator apparatus for multi-storied garage

Abstract

The invention discloses a hydraulic lifting device, in particular to an inversion type hydraulic relay lifting device for a stereo garage; the lifting device comprises a lifting frame and a lifting platform and is structurally characterized in that the lifting device is provided with multi-stage hydraulic cylinders; the stages of hydraulic cylinders are sequentially connected to form a loop; wherein, the oil cylinder of the top stage hydraulic cylinder is fixed with the top part of the lifting frame; the piston rod of the bottom stage of hydraulic cylinder is fixed with the lifting platform; the lifting platform can move up and down along the lifting frame; two groups of lifting frames are reversed U-shaped; four sets of multi-stage hydraulic cylinders are arranged on the lifting frame; each set of hydraulic cylinder is positioned at both ends of the lifting frame; support plates are connected between the hydraulic cylinders in the same stage of the two sets of the hydraulic cylinders mounted on the same lifting frame; the hydraulic cylinders in the same stage have simultaneous movement. The inversion type hydraulic relay lifting device for a stereo garage has the advantages of simple structure, stable operation, uneasy deformation, small friction, low noise and convenient operation.

Description

technical field [0001] The invention relates to a hydraulic lifting device, in particular to an inverted hydraulic relay lifting device for a three-dimensional garage. Background technique [0002] With the development of cities, three-dimensional garages are becoming more and more popular. The primary problem of realizing three-dimensional parking is to solve the problem of vehicle operation in vertical and horizontal two-dimensional space. Existing lifting devices for vertical space mainly use sprocket lifting system, hydraulic lifting system, etc. Among them, the sprocket lifting system has poor structural stability, the traction chain is easy to break and cause falling, high noise, easy wear, short life, and low positioning accuracy , the control system is complex and other disadvantages. The hydraulic lifting system uses the piston to push the vehicle into the upper floor. The cylinder is limited by the length-to-diameter ratio. Only one stage of oil cylinder is used, ...

AI Technical Summary

Problems solved by technology

The hydraulic lifting system adopted by the lifting frame, the piston rod is located above the hydraulic cylinder, and the hydraulic oil pushes the piston rod upwards to drive the vehicle up. The hydraulic cylinder cannot be made too thin, and it needs to cooperate with the sprocket lifting system and plug-in exchange. device to complete the entire lifting process, the structure is complex, the operation is cumbersome, the noise and friction are large
